When you order a crystal, you specify if you want the resonant frequency in series or parallel ... the inductor — so the model has actual practical application. By applying the usual formula ...
Simply put, inductors resist a change of current, and can act as a low pass filter when in series with the signal ... but not knowing the specific formula for calculating, I found this formula ...
In this chapter, the switched-mode second-order Class-E configurations with one capacitor and one inductor and generalized load network including the finite dc-feed inductance, shunt capacitance, and ...
